I was running my bat wing mower a few weeks ago and the tractor randomly started shutting off. I've owned this tractor since November and have only put about 6 hours on it myself so I don't know much of the history(It was included with our house) and it's the first diesel I've ever owned. I was pretty sure it was a fuel issue since the fuel filter was in pretty bad shape. I changed the filter, bled the lines and got nowhere. I have confirmed that I'm getting fuel to the injectors and the injectors have been cleaned. I've checked all the safety switches and there are no problems. I've also changed the fuel shut off solenoid, fuel shut off relay and the ignition switch. I'm running out of ideas and hope someone might be able to help me find somewhere else to look. Thanks in advance!
